An object of the invention is to provide a method for enabling MSn (n>) analysis of a trace amount of a sample and easily and rapidly obtaining structural information by identifying a bonding position of the labeling compound in a molecule with the MSn (n>) analysis. According to the present invention, by labeling a particular moiety of the molecule in a stable manner, ions are easily generated and stabilized, thereby improving sensitivity of the MS. The amount of precursor ions generated in this manner is an amount enough to carry out the MSn (n>1) analysis and to generate structure-specific ions with high reproducibility. The structural information can be easily and rapidly obtained with high sensitivity.
本发明的目的是提供一种方法,以便能够对痕量样品进行 MSn (n>)分析,并通过 MSn (n>)分析确定标记化合物在分子中的键合位置,从而方便快捷地获得结构信息。根据本发明,通过以稳定的方式标记分子中的特定分子,离子很容易产生和稳定,从而提高 MS 的灵敏度。以这种方式产生的前体离子量足以进行 MSn(n>1)分析,并能以较高的重现性产生结构特异性离子。这样就可以轻松、快速、高灵敏度地获得结构信息。
